Toleman/Benetton

The first Byrne-designed car to appear at a grand prix was the Hart-powered TG181. Lacking the finances to reach the first three long-haul races Toleman entered Formula One at the San Marino Grand Prix. Two seasons passed before the fledgling team began to score points, but by the conclusion of the 1983 season Derek Warwick and Bruno Giacomelli had collected a very respectable 10 points – enough for the team to finish ninth in the constructors' championship, and enough to earn Byrne credibility in the pit-lane. It was in the off-season of 1983/84 that Toleman signed Ayrton Senna – a move that almost made Byrne, Senna and the team first time winners at that year's Monaco Grand Prix.

The team's steady progress towards the front of the grid was given a boost in 1985 when the Benetton family announced plans to purchase Toleman. With more money, more resources and the most powerful engine available in the form of the inline-four turbocharged BMW, it took only until October 1986 for Gerhard Berger to secure the first win for himself, for the team and for a Byrne-designed car at the Mexican Grand Prix. Over the following five seasons, Byrne–designed cars took four more race wins but the Benetton team was never in a position to truly challenge the likes of Ferrari, Williams and McLaren, with most victories being taken on days when the competition faltered.

After a brief spell with the abortive Reynard F1 project in 1991 Byrne returned to Benetton that fall.^[1] What he found was a changed team now firmly under the control of Flavio Briatore and with hotshot Michael Schumacher installed as number one driver. Byrne's B193 car was a substantial technical advancement on the previous season's car, incorporating a semi-automatic gearbox, four-wheel steering, active suspension and traction control. The car took a single win in the hands of Schumacher, but everything was now in place for a title challenge in 1994. ^{[citation needed]}

It was immediately obvious^{[to whom?]} at the first race of 1994 that Byrne's B194 chassis would be the car to beat. Critics^[who?] suggested that the team's domination was more a result of an uncharacteristic slump by Williams star designer Adrian Newey and accusations of cheating^{[citation needed]} dogged the team for the entire season. A late-season charge by Williams robbed Byrne of his first constructors' title, but with his motto of "Evolution Not Revolution", everything seemed set for more success in 1995. ^{[citation needed]}

With the accusations of cheating behind them, the Benetton team secured both titles before the season was finished – finally Byrne had what he wanted most. His car had won the Formula One constructors' crown. With the hugely influential Schumacher leaving Benetton for Ferrari at the end of the season, the team began to fragment. Byrne announced that he would retire in 1996.

Ferrari

By the conclusion of the 1996 season Michael Schumacher was being given free rein at Ferrari to build a team of engineers capable of returning the team to the top of the sport after years of underperforming. Benetton technical director Ross Brawn was hired and Ferrari approached Rory Byrne to replace the team's existing chief designer John Barnard who refused to re-locate to Italy. After long negotiations Byrne was lured from his retirement in Thailand back to Europe where he began building a design office at Ferrari's Maranello headquarters. Ferrari were immediately competitive once again, taking the title fight to the final race of the season in both 1997 and 1998. Continuing to build momentum in the following seasons, Ferrari won the constructors' championship in 1999, their first in 17 years. By the end of the 2004 season, Byrne-designed Ferraris had secured 71 race victories, six consecutive constructors' titles and five consecutive drivers' titles for Michael Schumacher with a sustained level of dominance never before seen in the sport.

In 2004 Rory Byrne announced that he would be retiring from Formula One at the end of the 2006 season, handing over the role of chief designer to Aldo Costa, his assistant since 1998. On 19 September 2006, it was announced that Rory had extended his stay, as a consultant, at Ferrari for another two years which led him until early 2009.^[2]

In 2012, Byrne was called in to look at the Ferrari F2012 F1 car after it had a troubled start to its life.^[3] He was also involved in the design of LaFerrari.^[4]

In February 2013, at the launch of F138 – in interview to the German Auto Motor und Sport Rory Byrne said that he is "working full steam" on Ferrari's 2014 F1 car, in an advisory role.

Maurizio Arrivabene revealed that Byrne is working as mentor in Ferrari helping the chief designer Simone Resta.^[5]

Byrne was heavily involved in the design of the 2022 Ferrari F1-75. As the car proved successful on the first part of the season, his contract was renewed for further three years.^[6] He was also involved in the design of the 2023 Ferrari SF-23.
